Hereto'fore in they art, lUlIflSbBQHi custom:

any to remove the bull. rings byha nd' tools of. various descriptions.This has required the usein large factories; of a large number oiemployees for this specific: purpose, and

because of the difiiculty in breaking the. atl

hesion between the metal ring and the, rubher, great strength. andconsiderable; time has been required for this operation.

The chief object oi the present invention is to provide a machine forperforming the above operations and particularly a machine which ischeap to construct,easy toopera-te,

highly efficient to accomplishv the: purpose tiort whereby maintenance1310M}.

Another object is to. provide means for readily receiving and supportinga vulcanized: tire carrying the bull rings torprenent shifting ot thetire. axially and to. provide ring-engaging members movable: toward and!from the tire to. hookontothe.beadmings and pull them away from the tireaxially thereof.

Another object is to provide; a hookJiike ring pullingmembermovableoverthe bead ring axially of the tire, then: downwardlyinto engagement with the inner edge of the ring, then outwardly axiallyof the tire: to

separate the ring therefrom, then upwardly out of engagement with thering etc. I

The foregoing and ancillary'objects: are obtained by the constructionillustrated in the accompanying drawings and described in detail below.I It is to be understood" that the invention isnot limited to thespecific construction shown and described;v

suitable manner.

'18 inwardly carrying the hooks 16 mwardly The inner peripheries of therings 32 are;

spaced from each other as shown at 34: whereby when the hooks are movedoutwardly from the full line positions (Figure 3) they will drop bygravity into engagement with the inner edges of the rings 32 and oncontinued outward movement will draw the rings 32 away from tire 31 tothe dotted line positions shown in Figure 3. In order to then lift thehooks 16 out of engagement with rings 32 and to return them back ontostops 33 ready for the next operation, upon further movement of thehooks outwardly by cranks 18, each hook is formed with a projection 35,35 adapted to engage a rod 36, 36 in the path of each projection 35 andpositioned at'such apoint in said path as to effect upward swinging ofeach hook 16 by engagement with its'projection 35 after suiiieientseparation of the rings 32 from tire 31 is effected by the hooks. In theevent that the device should be actuated while no tire is positionedtherein, the walls 14 are formed as above described so that the hookswhich will drop into groove 12 will slide out of said groove when movedoutwardly without binding on casting 11.

The operation which will be understood from the foregoing may besummarized briefly as follows. Cured tires 31 having rings 32 thereonare rolled up one inclined groove 45 into the position shown in thedrawings in groove 12. The hooks 16 are normally in the outermost dottedline posit-ion shown in Figure 3. A single reciprocation of piston 25 isthen effected in any This first swings cranks until they drop by gravityonto the rings 32 as shown best in Figure 3. Then cranks 18 are swungoutwardly by the piston 25, first causing hooks 16 to drop in back ofthe inner edges of rings 32, then drawing the rings away from the tire31 as indicated by the dotted line positions thereof shown in F igure 3,walls 13 of groove 12 preventing any axial movement of tire 31. Aftersufficient separation of the rings 32 from the tire 31 has been thuseffected, continued move ment of the hooks outwardly causes projections35 to engage rods 36 whereby hooks 16 will swing upwardly out ofengagement with rings 32 onto the stops 33 where they will be maintainedby gravity until the next opera tion of the device.

The rings 32 are now lifted 05 the device with considerable difficultyand expense. '1'

The present inventor believes himself to be the first to devise amachine for performing such an operation and accordingly the appendedclaims should be construed liberally and broadly. It is accordinglyobvious that modifications of the invention may be resorted to withoutdeparting from the spirit thereof or the scope of the appended claims.
